Hi Rossco - I have 3 Owl PFs that I wired with telephone wire, and for me it was a lot easier than using stranded wire. The stranded stuff coils as it comes off the roll, and flops all over the place as you try to solder it. (Some guys even glue it first)
The trick to using telephone wire is to pre-bend it exactly into shape, and feed it out the camera case before you solder it. If you don't, it will tear loose from the trace when you try to bend it. And of course, if you flex solid wire too many times it will break. Somewhere in my WebSite I describe my process.
I agree with Richard, I myself wired a Owl PF and used telephone wire. With smaller soldering points the smaller wire makes it easier. Try using magnifying glass to help.But 26ga. is fine to.
What ever your comfortable with, after you use it once. you'll know if you want to mess with it again.
